(2) Cautions
1)
Be sure to connect a system controller.
2)
ME remote controller and MA remote controller cannot both be con-
nected to the same group of indoor units.
3)
Assign to the indoor units connected to the MA remote controller ad-
dresses that are smaller than those of the indoor units that are con-
nected to the ME remote controller.
4)
No more than 2 ME remote controllers can be connected to a group
of indoor units.
5)
No more than 2 MA remote controllers can be connected to a group
of indoor units. It is not possible to connect a pair of PAR-30MAAU.
6)
Do not connect the terminal blocks (TB5) on the indoor units that are
connected to different outdoor units with each other.
7)
Replace the power jumper connector of the control board from CN41
to CN40 on only one of the outdoor units.
8)
Provide an electrical path to ground for the S terminal on the terminal
block for centralized control on only one of the outdoor units.
9)
When the number of the connected indoor units is as shown in the
table below, one or more transmission boosters (sold separately)
are required.
To connect two transmission boosters, connect them in parallel.
(Observe the maximum number of connectable indoor units that are

The left table shows the number of transmission boost-
ers that is required by the system with three BC control-
lers. For each BC controller that is subtracted from the
above-mentioned system, two additional indoor units
can be connected.
Refer to the DATABOOK for further information about
how many booster units are required for a given system.
10) When a power supply unit is connected to the transmis-
sion line for centralized control, leave the power jumper
connector on CN41 as it is (factory setting).
